Abstract: A hinge includes two rotatable axle units disposed on a base seat and each having two rotatable hinge shafts, two movable bracket units each including a base plate, two rotary blocks non-rotatably sleeved on the hinge shafts, and two movable plates movable relative to the rotary blocks, and two synchronizing units for making synchronous rotations of the hinge shafts. Each synchronizing unit includes a first gear member having two end surfaces in form of bevel gears, and two second gear members each meshing with the respective end surface and fitted to the respective rotary block. Rotations of the hinge shafts at one side of the base seat result in rotations of the rotary blocks and the second gear members, and bring in rotations of the second gear members, the rotary blocks and the hinge shafts at the other side to make the synchronous rotations.

Abstract: An electronic device includes a base cover, a cover plate which is slidable relative to the base cover among a closed position, an open position, and a transition position, and a slide positioning mechanism which is configured for positioning the cover plate relative to the base cover, and which has first and second magnetically attractive units. When the cover plate is in a selected one of the closed and open positions, a magnetically attractive force is generated to position the cover plate in the selected one of the closed and open positions. When the cover plate is in the transition position, a magnetically repulsive force is generated to facilitate movement of the cover plate away from the transition position.

Abstract: A hinge includes two rotatable axle units each having two hinge shafts, two synchronizing units each disposed to make synchronous rotations of the hinge shafts, two movable bracket units each having a turnable base plate, two rotary blocks non-rotatably sleeved on the hinge shafts, and two movable plates movable relative to the rotary blocks, and two guiding bracket units, each having male and female arms respectively connected with two movable plates, and a plurality of guiding connecting members interposed between the arms. Each guiding connecting member has a protrusion and a sliding groove, and is angularly movable with the rotations of the hinge shafts. Removal of the protrusion from the sliding groove of an adjacent guiding connecting member is prevented by means of engagement of an abutting portion of the protrusion with an abutted block in the groove.
